A bit of good news. The bed printing area has thus far been artificially restricted to 10" X 18.5". There are plans to slowly increase it toward a goal of 11.5 X 20.4". The limit was increased today to 11" X 19.5" and I can confirm it cuts to those dimensions. Apparently the company is working toward the plan.
I have no idea whether all of the units produced have the same S/W limits.
